Apparently TV producers, that’s who. From both ends of the Keystone State come two new dramas – “The Guardian” from Pittsburgh and “Philly” from Philadelphia.

“Philly” – premiering tonight at 10 on ABC – looks like the City of Brotherly Love, but doesn’t sound like it because not one of the actors seems to have been coached in the classic Philadelphia accent (pronounce “Tuesday” as “Tues-dee” and you’ve made a start).

But it must be Philadelphia (my mother always frowned on calling our hometown “Philly”) since we see some of the city’s landmarks – the Benjamin Franklin Bridge, Independence Hall, City Hall – in an opening montage.

That, of course, is the Steven Bochco formula. Come to the city in which you’ve placed your series to shoot exteriors for a few days. Then shoot all the rest of it back home in California.

Look, it works for “NYPD Blue” and it works here too. In “Philly,” Kim Delaney stars as a harried attorney who’s juggling too many cases and running pell-mell around the corridors of Philadelphia’s labyrinthine city hall.

That’s part of the Bochco formula, too. People do so much business on the fly in “Philly” that it will leave you breathless.

If Philadelphians were really this energetic, Men’s Fitness magazine might never have pegged the city’s residents as the nation’s fattest citizens.

And if many Philadelphians really are obese, Kim Delaney is definitely not one of them.

It’s 308 miles from Philadelphia City Hall to the Allegheny County Court House that is the milieu for “The Guardian,” whose 9 o’clock timeslot would make it the keystone of CBS’s Tuesday night lineup.

The title refers to a young attorney, Nicholas Fallin – played by the charismatic Simon Baker – who’s performing 1,500 hours of community service as an advocate for children as punishment for a drug conviction. At the same time, he’s still holding down his real job, as a rising star of his father’s law firm.

In tonight’s opener, Nick meets his first child client, a boy who witnessed his plastic-surgeon father stab his mother to death.

While the ensuing custody case might have proceeded in any number of predictable ways, the outcome of this one is not what you would expect from a lifetime of lawyer shows.

While “The Guardian” comes to television with its heart in the right place, the premiere episode is marred by a strange and off-putting obsession with urination.

On two occasions, Nick announces that he must “take a leak.” In a third reference, he is ordered to the urinal with a vial to be filled for testing purposes.

If the makers of “The Guardian” can get their minds out of the men’s room, this series has potential.
